    • Databases of Physical Constants

  • Databases available through the WSU library Includes on-line archive of all ACS journals!
  • CHEMnetBASE. Try the Properties of Organic Compounds database.
  • http://www.emolecules.com/ Allows one to search for information by drawing the structure of the compound.
  • ChemIDPlus. Detailed toxicity data for 139,000 common compounds.
  • When all else fails try googling it! www.google.com
  • GoogleScholar is a great way to access the primary literature.

    Spectroscopy Databases

  • Database of Mass, IR, ESR, and NMR Spectra: NIMCR's ISDBS for Organic Compounds
  • Sigma-Aldrich also has NMR spectra: www.SigmaAldrich.com
  • Chemical Shifts compilation: http://www.chem.wisc.edu/areas/organic/index-chem.htm
  • NMR Chemical Shifts of Trace Impurities: Common Laboratory Solvents, Organics, and Gases in Deuterated Solvents
  • Database of IR and Mass Spectra. NIST Chemistry WebBook
  • NMR Spectrum Predictor** http://www.nmrdb.org/new_predictor/index.shtml?v=v2.82.3
    **Do not put too much credence in the NMR predictors. These use empirical parameterization "i.e., fudge factors" (similar to the method described on pp 387-389 of the Mohrig lab text) to predict chemical shifts. The results obtained cannot by any stretch be used as "literature", or "theoretical" values. However, sometimes they can be used as a rough estimate of where your peaks should be.
